Because he is loyal to his nation, he wanted Turkey to be a force again and he managed to do it .. Turkey voice now is respected and its economy is one of the most powerful in the world.
Funny you should say that, if by respected you mean joke who everyone suspects of being on the same side as ISIS, then yes sure, respected.
We had this thing here recently, you might have heard about it, Brexit, the referendum, a vote if the UK wanted to remain in the EU or not? Well, one of the big selling points that got people to vote to leave is the potential that Turkey might one day be allowed in. Millions of people in this country respect Turkey soooo much, they would rather set themselves on fire and jump off a cliff than be in a club you might, just might be allowed into.
Funny thing is that you never will be, for lots of reasons. But currently because your leader is a despotic nutcase who cant a joke and everyone thinks your country a friend of terrorists. If not actually aiding them, then turning a blind eye enabling them to go back and forth, smuggle oil, people traffic and get into western Europe to murder people in the street.
If Turkey wasnt strategically important to NATO and the oil industry, the sky would be full of USAF Reaper drones.
If it goes full radical, America and NATO will have to pull out. Cant risk the nukes stationed there falling into the wrong hands. Then its at the mercy of ISIS and Russia, and will likely fall into the chaos thats going on in the rest of the region.
